"Imagine a young person very attractive and a little uncertain. Imagine further a mother of this only child a little hovering, a little too eager to be helpful and advisory. This not uncommon situation puts the young person at risk of what we can term "imagined incapacity": the half conviction of being unable to do all sorts of things that in fact she probably can do." Leston Havens, "Freud's Invention"
This "imagined incapacity" creates all kinds of symptoms such as anxiety and depression. There is a learned helplessness which takes persistent effort to overcome. Psychotherapy helps.
